Infineon Technologies CY7C68015A-56PVXC

Overview

CY7C68015A-56PVXC from Infineon Technologies (formerly Cypress Semiconductor) is a high-speed USB 2.0 peripheral controller integrating an enhanced 8051 microprocessor, USB 2.0 transceiver, serial interface engine (SIE), and General Programmable Interface (GPIF) in a single 56-pin QFN package. It supports 480 Mbps signaling, delivers up to 53 MB/s data throughput, features 16 KB on-chip RAM, 4 programmable endpoints with double/triple/quad buffering, and operates at 12/24/48 MHz CPU clock. It is used in USB-to-ATA, USB-to-FPGA, and embedded host bridge applications requiring glueless parallel interface control.

For engineers reviewing the CY7C68015A-56PVXC datasheet, CY7C68015A-56PVXC pinout, CY7C68015A-56PVXC application, or CY7C68015A-56PVXC equivalent, key selection criteria include its 56-pin QFN footprint with 26 GPIOs, GPIF waveform programmability for custom bus timing, suspend current of 300 µA (typ), I²C controller (100/400 kHz), and slave FIFO support for 8-/16-bit external memory or ASIC interfacing.

Technical Context

The CY7C68015A implements a hardware-accelerated USB 2.0 stack via its Smart Serial Interface Engine (SIE), offloading protocol handling from the 8051 core and enabling deterministic endpoint management. Its GPIF operates independently of the CPU, using configurable waveform descriptors to generate precise control and strobe signals for parallel interfaces like ATA, EPP, or SRAM.

It supports four USB transfer types-BULK, INTERRUPT, ISOCHRONOUS, and CONTROL-with dedicated dual-port FIFOs per endpoint and separate setup/data buffers for CONTROL transfers. The integrated I²C controller runs at nominal 100 kHz or 400 kHz (measured ~85 kHz / ~300 kHz), and the 8051 core executes instructions at four clocks per cycle with two data pointers and expanded interrupt vectors.

FAQ

Is CY7C68015A-56PVXC pin-compatible with CY7C68013A-56PVXC?

Yes, CY7C68015A-56PVXC is pin-compatible with CY7C68013A-56PVXC in the 56-pin QFN package. Both share identical pin assignments for USB, GPIF, Slave FIFO, and power functions. The CY7C68015A adds two GPIOs (PORTD.6 and PORTD.7) mapped to unused pins in the CY7C68013A layout, preserving mechanical and electrical compatibility while extending functionality.

Does CY7C68015A support USB host functionality?

No, CY7C68015A is a USB 2.0 peripheral-only controller and does not implement USB host or OTG capabilities. It operates exclusively in device mode, enumerating as a USB device under host control. Host-side functionality requires external USB host controllers such as the SMSC USB334x or Microchip USB5744.

What is the maximum achievable data throughput using Slave FIFO mode?

In Slave FIFO mode with 16-bit data bus and synchronous timing, CY7C68015A achieves up to 48 MB/s sustained throughput using BULK transfers. This is constrained by USB 2.0 protocol overhead and host controller efficiency-not by the chip's internal FIFO or GPIF bandwidth, which supports bursts exceeding 90 MB/s in ideal conditions.

Can the onboard 8051 execute code directly from external memory?

No, the CY7C68015A's 8051 core executes only from internal RAM or external memory accessed via GPIF or Slave FIFO - not from external program memory mapped in Harvard architecture. Firmware must be loaded into on-chip RAM at boot (via USB, EEPROM, or external memory) before execution begins.
